DAB PULSAR DRY Multistage Submersible Pumps
The PULSAR DRY pumps are used in lifting and
pressurisation systems for water from primary collection
tanks or wells and are suitable for providing pressurized
water in domestic systems, small-scale farming and
sprinkler systems for gardens and vegetable gardens. The
pump is extremely silent and this feature makes it suitable
for use with pressurisation systems in unventilated rooms
or in areas prone to flooding. Single-piece multi-stage
bore-hole pump or of surface with hydraulic assembly
positioned under the motor which is cooled by the pumped
liquid. Impellers, diffusers, filter and oil sump in abrasionproof
thermoplastic. Pump liner, stator sleeve, upper head
with sleeve and sealing ring in AISI 304 steel. Upper and
lower bearing supports in dezincification-proof pressed
brass. Rotor shaft extension in AISI 304. Elastomers in
NBR. Stainless steel hardware. Double mechanical
seal separated by an oil chamber, in ceramic/carbon
on the motor side and carburundum/carburundum on
the pump side. The sealing system ensures the motor
remains airtight and the mechanical seal holds even after
brief periods of no-water operation.
Continuous service asynchronous submersible motor.
Stator incorporated in an AISI 304 stainless steel airtight
casing with a cover housing the cables and capacitor.
Rotor mounted on oversized ball bearings to ensure
silent running and long life. Incorporated thermal current
protection and permanently connected capacitor in the
single-phase version. As regards three-phase protection,
a motor overload cut out should be fitted, in accordance
with current standards. Built to IEC 2-3 and IEC 61-69

SCHUKO EEC 7-VII-UNEL 47166-68 plug for the singlephase
version. The single-phase versions can be supplied
with or without floats for automatic operation.
